What are iso files, and how do I open them?

Hi guys,
I have an iso file also and I managed to open it with Undisker...a piece of software that I found on google search.
See if that helps

Hey Guys,
There is a software Named PowerIso or MagicISo
All Of You Can Open .ISO files , .Bin and ...
There

Thanks

i just downloaded a software program to help with my uni study. its a human anatomy and physiology cd. its one big iso file and ive managed to unzip its contents but how do i burn it to disc as though it was just bought off the shelf?? do i put all the files that were unzipped on the disc or is there something else i need to do?

I have DVd's with video images - I'm trying to import them so I can edit them. Windows Movie Maker doesn't recognize them so I downloaded them onto my computer - still no luck. They saved as ISO files. Now what? They play just fine in Windows Media Player.

I had to format my PC, before that my ISO files appeared like ABCDEF.ISO; right now after the format they appear as a RAR file so my questions here how do I do to put the things the way they were? and sorry my ignorance about it; is this a real problem?.
I appreciate your help. Thanks
